Title: Optical head device in which recorded state can be confirmed at the time of recording
Inventor: MATSUI TSUTOMU
IPC: G11B11/10
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide an optical head which can confirm a recording state at the time of recording using a single beam laser. SOLUTION: In a phase variation light head, a recording state is confirmed based on a signal in which outgoing light from a laser 101 and reflected light from an optical disk 109 are differentially detected. Two optical sensors 112, 115 are arranged at the same position in a light path system to take matching between this differential amplifier 118 and two optical sensors 112, 115. Differential output between a signal detected from surface reflected light of a complex prism 107 in which a beam of outgoing light from the laser is formed and a signal detected from reflected light from the optical disk is obtained, a D type flip-flop is triggered by rise and fall of this signal, and a signal already recorded is detected.

Abstract: PURPOSE:To obtain a contact structure having a high density and high reliability, by narrowing the boundary part between a substrate main surface and a polycrystalline Si pattern of the common open region in which a metal contact is provided. CONSTITUTION:On the main surface of a substrate 1 having a diffused layer 2, a polycrystalline Si pattern 5 is formed through an oxide film, on which an oxide film 3 for interlayer insulation is provided. An opening 7 is formed in said film 3 to form a contact electrode common to the diffused layer 2 and the pattern 5 by means of, for example, an Al layer 4. The opening 7 is so formed that a part 11 extending over the boundary part 10 between the pattern 5 and the substrate surface has a narrow neck shape. Therefore, a steep slope is formed at the neck part 11 as shown in the section A-A', however, such slope that may disconnect the Al layer 4 can be prevented from being formed at the neck part 11 as shown in the section B-B'. Thus, a minute contact structure having good contactability and hgih reliability can be obtained.

Abstract: PURPOSE:To facilitate the formation of a groove on a substrate by alternately repeating the step of selectively etching the substrate by a dry etching method using a gas plasma and the step of forming a film on the surface to be etched with the plasma. CONSTITUTION:A silicon oxide film 2 is formed on a substrate 1, and etched with a patterned resist 3 as a mask. With the film 2 as a mask the substrate 1 is etched by a reactive ion etching method (by employing Cl2 for reactive gas). When the etching is stopped, the reaction gas is instead substituted for O2 and treated in a plasma atomosphere, a thin oxide film 5 is formed on the inner surface of a groove 4. When the reaction gas is again substituted for Cl2 in this state, the bottom of the groove 4 is progressively etched by ion implantation in a plasma to form a deep groove 4'. Thus, an ultrafine deep perpendicular groove is formed.

IPC: F16F13/00
Filed: 1983-06-10
Abstract: PURPOSE:To suitably suppress or isolate vibration of an engine in the all running condition of a vehicle, by variably controlling the moving distance of a movable separator plate arranged between fluid chambers in accordance with an operating condition of the engine. CONSTITUTION:As a rotary shaft 11, eccentrically shaped by forming its center into a small contour part, turns the small contour part eccentrically rotates, and a cylindrical member 7 vertically moves to adjust an opposed distance between stopper faces 43a, 71a, thus controlling the moving distance of a movable separator plate 10. Since the second fluid chamber B forms its chamber wall by a freely deformable elastic sheet 8 of rubber in small thickness, a change of internal pressure in the first fluid chamber A can be absorbed by movement of the movable separator plate 10 when its movement is controlled to a large distance. If the movement of the movable separator plate 10 is controlled to a small distance, the change of the internal pressure in the first fluid chamber A can not be absorbed by the movable separator plate 10, and the fluid chamber A communicates to the third fluid chamber C, forming its chamber wall by an elastic material sheet 9 of rubber in large thickness, through a throttling hole F, thus large damping force of vibration is generated.

Title: Instrument for measuring film thickness
Inventor: ITONAGA MAKOTO
IPC: G01B11/06
Filed: 1984-05-24
Abstract: PURPOSE:To measure film thickness with high accuracy in short time by setting the incident angle of the light from a light source at the angle equal to or approximate to the polarizing angle of a transparent film to be measured which is determined from the refractive index of the transparent film to be measured. CONSTITUTION:The incident angle of the light from the light source 7 is selected by the angle equal to or approximate to the polarizing angle of the film 3 to be measured which is determined from the refractive index of the film 3 in a film thickness measuring instrument. The film thickness size corresponding to certain measured values DELTA, PSI is just one if the refractive index of, for example, a transparent substrate 4 is assumed to be 1.52 and the refractive index of the film 3 to be 1.63 and if the measured values when the incident angle of the light from the light source 7 is set at the angle approximate to the polarizing angle are designated as DELTA, PSI, The change rate of the film thickness size corresponding to the change of the value DELTA is small and the correspondence between the measured value DELTA and the film thickness size is much higher in accuracy than heretofore. The measurement of the film thickness with high accuracy in short time is thus made possible according to the above-mentioned instrument.

Title: Governor follow-up device for back pressure turbine
Inventor: MIZUKAMI HIDEYUKI
IPC: F01K7/38
Filed: 1991-04-11
Abstract: PURPOSE:To prevent increase of a rotational number of a back pressure turbine during shifting from a pressure governing operation to a speed governing operation, and also prevent a remarkable change of a back pressure by adding a bias signal from a bias setter to a sum of a load setting signal and a speed controlling signal during the pressure governing operation, and providing a means for subtracting the bias signal during the speed governing operation. CONSTITUTION:A motion controlling system B is provided with a bias setter 18, an adder 19 and a pressure governing operation contact point 20. The bias setter 18 outputs a specified value of bias signal S10. The adder 19 adds the bias signal S10 from the bias setter 18 during a pressure governing operation. The pressure governing operaction contact point 20 is closed during the pressure governing operation, and opened during parallel off. When the pressure governing operation is changed over to a speed governing operation by the parallel off, the pressure governing operation contact point 20 is opened. Thus, the bias signal S10 is not input to the adder 19, and a back pressure controlling signal S8 is not input to a lower value preference circuit 12. As a result, a speed governing controlling signal S11 speedily approaches a level of the back pressure controlling signal S8 during the pressure governing operation, and follows it Up.

Abstract: PURPOSE: To enable staples to be rapidly loaded and released and appropriately applied to tissue by causing a stapler former to be spring-pressed against a staple holder. CONSTITUTION: A holder 24 is spring-pressed against a former 26, and the former 26 and the holder 24 are slidable with respect to a stationary anvil 28. The stationary anvil 28 has at its end an anvil part 30 in which a staple 20 is formed, and the holder 24 has a rack 32 on which the crown 34 of the staple 20 is seated. The holder 24 maintains the staple crown 34 relative to the anvil part 30, and by squeezing the trigger of a restoration mechanism a former leg 36 makes contact with the staple 20 at the end of the crown 34, forming the staple 20 completely around the anvil part 30. The camming part 38 of the former 26 placed beneath the holder 24 is close to the camming part 40 of the holder 24. Thus, a restoration device prepares staples 20 in sequence for release after formation.
